Public bug reported:
On Ubuntu 16.04.x, I have a perfectly working custom systemd service
file which sets username and group for the service as
[Service]
User=user
Group=domain users
where both group and user come from an AD domain joined to with winbind.
This is not working anymore on 18.04. Even with the group name quoted,
or mangled with systemd-escape. The service doesn't start with one of
the following messages in the journal (depending on how it's spelled):
/lib/systemd/system/myservice.service:11: Invalid user/group name or numeric
ID: domain users
/lib/systemd/system/myservice.service:11: Invalid user/group name or numeric
ID: "domain users"
/lib/systemd/system/myservice.service:11: Invalid user/group name or numeric
ID: domain\x20users
/lib/systemd/system/myservice.service:11: Invalid user/group name or numeric
ID: domain\ users
The only thing that works is to use the GID instead of the group name.
